According to a study by the Nutrition Business Journal of San Diego, in 1997 sales of dietary supplements, natural foods and natural personal care items totaled $65 billion worldwide, and the USA had consumer sales of $23 billion.

Comment: Information on the boom times being enjoyed by the dietary supplement industry is prelude to the following enormously important sets of guides being promulgated by the two major federal regulatory agencies responsible for consumer protection in the United States.
The guidelines originally appeared in the FDA Consumer, Sept-Oct, 1998, but the following contains revisions made in January 1999.
Set between a Chinese restaurant and a pizza and sub sandwich eatery, a Rockville health food store offers yet another brand of edible items: Bottled herbs like cat's claw, dandelion root, and blessed thistle. Vitamins and minerals in varying doses. Herbal and nutrient concoctions whose labels carry claims about relieving pain, "energizing" and "detoxifying" the body, or providing "guaranteed results." This store sells dietary supplements, some of the hottest selling items on the market today. Surveys show that more than half of the U.S. adult population uses these products. In 1996 alone, consumers spent more than $6.5 billion on dietary supplements, according to Packaged Facts Inc., a market research firm in New York City. But even with all the business they generate, consumers still ask questions about dietary supplements: Can their claims be trusted? Are they safe? Does the Food and Drug Administration approve them?
Many of these questions come in the wake of the 1994 Dietary Supplement Health and Education Act, or DSHEA, which set up a new framework for FDA regulation of dietary supplements. It also created an office in the National Institutes of Health to coordinate research on dietary supplements, and it called on President Clinton to set up an independent dietary supplement commission to report on the use of claims in dietary supplement labeling.
In passing DSHEA, Congress recognized first, that many people believe dietary supplements offer health benefits and second, that consumers want a greater opportunity to determine whether supplements may help them. The law essentially gives dietary supplement manufacturers freedom to market more products as dietary supplements and provide information about their products' benefits--for example, in product labeling.
The Council for Responsible Nutrition, an organization of manufacturers of dietary supplements and their suppliers, welcomes the change. "Our philosophy has been ... to maintain consumer access to products and access to information [so that consumers can] make informed choices," says John Cordaro, the group's president and chief executive officer. But in choosing whether to use dietary supplements, FDA answers consumers' questions by noting that under DSHEA, FDA's requirement for premarket review of dietary supplements is less than that over other products it regulates, such as drugs and many additives used in conventional foods. This means that consumers and manufacturers have responsibility for checking the safety of dietary supplements and determining the truthfulness of label claims.
Information that will be required on the labels of dietary supplements includes: Statement of identity (eg, "ginseng"); Net quantity of contents (eg, "60 capsules"); Structure-function claim and the statement "This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease"; Directions for use (eg, "Take one capsule daily"); Supplement Facts panel (lists serving size, amount, and active ingredient); Other ingredients in descending order of predominance and by common name or proprietary blend; Name and place of business of manufacturer, packer or distributor. This is the address to write for more product information.
Traditionally, dietary supplements referred to products made of one or more of the essential nutrients, such as vitamins, minerals, and protein. But DSHEA broadens the definition to include, with some exceptions, any product intended for ingestion as a supplement to the diet. This includes vitamins; minerals; herbs, botanicals, and other plant-derived substances; and amino acids (the individual building blocks of protein) and concentrates, metabolites, constituents and extracts of these substances. It's easy to spot a supplement because DSHEA requires manufacturers to include the words "dietary supplement" on product labels. Also, starting in March 1999, a "Supplement Facts" panel will be required on the labels of most dietary supplements. Dietary supplements come in many forms, including tablets, capsules, powders, softgels, gelcaps, and liquids. Though commonly associated with health food stores, dietary supplements also are sold in grocery, drug and national discount chain stores, as well as through mail-order catalogs, TV programs, the Internet, and direct sales. FDA oversees safety, manufacturing and product information, such as claims, in a product's labeling, package inserts, and accompanying literature. The Federal Trade Commission regulates the advertising of dietary supplements. One thing dietary supplements are not is drugs. A drug, which sometimes can be derived from plants used as traditional medicines, is an article that, among other things, is intended to diagnose, cure, mitigate, treat, or prevent diseases. Before marketing, drugs must undergo clinical studies to determine their effectiveness, safety, possible interactions with other substances, and appropriate dosages, and FDA must review these data and authorize the drugs' use before they are marketed. FDA does not authorize or test dietary supplements. A product sold as a dietary supplement and touted in its labeling as a new treatment or cure for a specific disease or condition would be considered an unauthorized--and thus illegal--drug. Labeling changes consistent with the provisions in DSHEA would be required to maintain the product's status as a dietary supplement. Another thing dietary supplements are not are replacements for conventional diets, nutritionists say. Supplements do not provide all the known--and perhaps unknown--nutritional benefits of conventional food.
As with food, federal law requires manufacturers of dietary supplements to ensure that the products they put on the market are safe. But supplement manufacturers do not have to provide information to FDA to get a product on the market, unlike the food additive process often required of new food ingredients. FDA review and approval of supplement ingredients and products is not required before marketing. Food additives not generally recognized as safe must undergo FDA's premarket approval process for new food ingredients. This requires manufacturers to conduct safety studies and submit the results to FDA for review before the ingredient can be used in marketed products. Based on its review, FDA either authorizes or rejects the food additive. In contrast, dietary supplement manufacturers that wish to market a new ingredient (that is, an ingredient not marketed in the United States before 1994) have two options. The first involves submitting to FDA, at least 75 days before the product is expected to go on the market, information that supports their conclusion that a new ingredient can reasonably be expected to be safe. Safe means that the new ingredient does not present a significant or unreasonable risk of illness or injury under conditions of use recommended in the product's labeling. The information the manufacturer submits becomes publicly available 90 days after FDA receives it. Another option for manufacturers is to petition FDA, asking the agency to establish the conditions under which the new dietary ingredient would reasonably be expected to be safe. To date, FDA's Center for Food Safety and Applied Nutrition has received no such petitions.
Under DSHEA, once a dietary supplement is marketed, FDA has the responsibility for showing that a dietary supplement is unsafe before it can take action to restrict the product's use. This was the case when, in June 1997, FDA proposed, among other things, to limit the amount of ephedrine alkaloids in dietary supplements (marketed as ephedra, Ma huang, Chinese ephedra, and epitonin, for example) and provide warnings to consumers about hazards associated with use of dietary supplements containing the ingredients. The hazards ranged from nervousness, dizziness, and changes in blood pressure and heart rate to chest pain, heart attack, hepatitis, stroke, seizures, psychosis, and death. The proposal stemmed from FDA's review of adverse event reports it had received, scientific literature, and public comments. FDA has received many comments on the 1997 proposal and was reviewing them at press time. Also in 1997, FDA identified contamination of the herbal ingredient plantain with the harmful herb Digitalis lanata after receiving a report of a complete heart block in a young woman. FDA traced all use of the contaminated ingredient and asked manufacturers and retailers to withdraw these products from the market. (For information about other potentially dangerous dietary supplements, see "Supplements Associated with Illnesses and Injuries which is an Internet location. DSHEA also gives FDA authority to establish good manufacturing practices, or GMPs, for dietary supplements. In a February 1997 advance notice of proposed rulemaking, the agency said it would establish dietary supplement GMPs if, after public comment, it determined that GMPs for conventional food are not adequate to cover dietary supplements, as well. GMPs, the agency said, would ensure that dietary supplements are made under conditions that would result in safe and properly labeled products. At press time, FDA was reviewing comments on the 1997 notice. Some supplement makers may already voluntarily follow GMPs devised, for example, by trade groups. Besides FDA, individual states can take steps to restrict or stop the sale of potentially harmful dietary supplements within their jurisdictions. For example, Florida has banned some ephedra-containing products, and other states have said they are considering similar action. Also, the industry strives to regulate itself, the Council for Responsible Nutrition's Cordaro says. He cites the GMPs that his trade group and others developed for their member companies. FDA is reviewing these GMPs as it considers whether to pursue mandatory industry-wide GMPs. Another example of self-regulation, Cordaro says, is the voluntary use of a warning about ephedra products that his organization drafted. He says that about 90 percent of U.S. manufacturers of products containing ephedra alkaloids now use this warning label.
Claims that tout a supplement's healthful benefits have always been a controversial feature of dietary supplements. Manufacturers often rely on them to sell their products. But consumers often wonder whether they can trust them. Under DSHEA and previous food labeling laws, supplement manufacturers are allowed to use, when appropriate, three types of claims: nutrient-content claims, disease claims, and nutrition support claims, which include "structure-function claims." Nutrient-content claims describe the level of a nutrient in a food or dietary supplement. For example, a supplement containing at least 200 milligrams of calcium per serving could carry the claim "high in calcium." A supplement with at least 12 mg per serving of vitamin C could state on its label, "Excellent source of vitamin C." Disease claims show a link between a food or substance and a disease or health-related condition. FDA authorizes these claims based on a review of the scientific evidence. Or, after the agency is notified, the claims may be based on an authoritative statement from certain scientific bodies, such as the National Academy of Sciences, that shows or describes a well-established diet-to-health link. As of this writing, certain dietary supplements may be eligible to carry disease claims, such as claims that show a link between: the vitamin folic acid and a decreased risk of neural tube defect-affected pregnancy, if the supplement contains sufficient amounts of folic acid; calcium and a lower risk of osteoporosis, if the supplement contains sufficient amounts of calcium; psyllium seed husk (as part of a diet low in cholesterol and saturated fat) and coronary heart disease, if the supplement contains sufficient amounts of psyllium seed husk.
Nutrition support claims can describe a link between a nutrient and the deficiency disease that can result if the nutrient is lacking in the diet. For example, the label of a vitamin C supplement could state that vitamin C prevents scurvy. When these types of claims are used, the label must mention the prevalence of the nutrient-deficiency disease in the United States. These claims also can refer to the supplement's effect on the body's structure or function, including its overall effect on a person's well-being. These are known as structure-function claims. Examples of structure-function claims are: Calcium builds strong bones. Antioxidants maintain cell integrity. Fiber maintains bowel regularity.
Manufacturers can use structure-function claims without FDA authorization. They base their claims on their review and interpretation of the scientific literature. Like all label claims, structure-function claims must be true and not misleading. Structure-function claims can be easy to spot because, on the label, they must be accompanied with the disclaimer "This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease." Manufacturers who plan to use a structure-function claim on a particular product must inform FDA of the use of the claim no later than 30 days after the product is first marketed. While the manufacturer must be able to substantiate its claim, it does not have to share the substantiation with FDA or make it publicly available. If the submitted claims promote the products as drugs instead of supplements, FDA can advise the manufacturer to change or delete the claim. Because there often is a fine line between disease claims and structure-function claims, FDA in April 1998 proposed regulations that would establish criteria under which a label claim would or would not qualify as a disease claim. Among label factors FDA proposed for consideration are: the naming of a specific disease or class of diseases; the use of scientific or lay terminology to describe the product's effect on one or more signs or symptoms recognized by health-care professionals and consumers as characteristic of a specific disease or a number of different specific diseases; product name; statements about product formulation; citations or references that refer to disease; use of the words "disease" or "diseased" art, such as symbols and pictures; statements that the product can substitute for an approved therapy (for example, a drug).
FDA's proposal is consistent with the guidance on the distinction between structure-function and disease claims provided in the 1997 report by the President's Commission on Dietary Supplement Labels. If shoppers find dietary supplements whose labels state or imply that the product can help diagnose, treat, cure, or prevent a disease (for example, "cures cancer" or "treats arthritis"), they should realize that the product is being marketed illegally as a drug and as such has not been evaluated for safety or effectiveness.
FTC regulates claims made in the advertising of dietary supplements, and in recent years, that agency has taken a number of enforcement actions against companies whose advertisements contained false and misleading information. The actions targeted, for example, erroneous claims that chromium picolinate was a treatment for weight loss and high blood cholesterol. An action in 1997 targeted ads for an ephedrine alkaloid supplement because they understated the degree of the product's risk and featured a man falsely described as a doctor.
Consumers need to be on the lookout for fraudulent products. These are products that don't do what they say they can or don't contain what they say they contain. At the very least, they waste consumers' money, and they may cause physical harm. Fraudulent products often can be identified by the types of claims made in their labeling, advertising and promotional literature. Some possible indicators of fraud, says Stephen Barrett, M.D., a board member of the National Council Against Health Fraud, are: Claims that the product is a secret cure and use of such terms as "breakthrough," "magical," "miracle cure," and "new discovery." If the product were a cure for a serious disease, it would be widely reported in the media and used by health-care professionals, he says. "Pseudomedical" jargon, such as "detoxify," "purify" and "energize" to describe a product's effects. These claims are vague and hard to measure, Barrett says. So, they make it easier for success to be claimed "even though nothing has actually been accomplished," he says.
Claims that the product can cure a wide range of unrelated diseases. No product can do that, he says. Claims that a product is backed by scientific studies, but with no list of references or references that are inadequate. For instance, if a list of references is provided, the citations cannot be traced, or if they are traceable, the studies are out-of-date, irrelevant, or poorly designed. Claims that the supplement has only benefits--and no side effects. A product "potent enough to help people will be potent enough to cause side effects," Barrett says. Accusations that the medical profession, drug companies and the government are suppressing information about a particular treatment. It would be illogical, Barrett says, for large numbers of people to withhold information about potential medical therapies when they or their families and friends might one day benefit from them. Though often more difficult to do, consumers also can protect themselves from economic fraud, a practice in which the manufacturer substitutes part or all of a product with an inferior, cheaper ingredient and then passes off the fake product as the real thing but at a lower cost. Varro Tyler, Ph.D., Sc.D., a distinguished professor emeritus of pharmacognosy (the study of medicinal products in their crude, or unprepared, form) at Purdue University in West LaFayette, Ind., advises consumers to avoid products sold for considerably less money than competing brands. "If it's too cheap, the product is probably not what it's supposed to be," he says.
Poor manufacturing practices are not unique to dietary supplements, but the growing market for supplements in a less restrictive regulatory environment creates the potential for supplements to be prone to quality-control problems. For example, FDA has identified several problems where some manufacturers were buying herbs, plants and other ingredients without first adequately testing them to determine whether the product they ordered was actually what they received or whether the ingredients were free from contaminants.
Consumers who use dietary supplements should always read product labels, follow directions, and heed all warnings. Supplement users who suffer a serious harmful effect or illness that they think is related to supplement use should call a doctor or other health-care provider. He or she in turn can report it to FDA MedWatch by calling 1-800-FDA-1088 or going to www.fda.gov/medwatch/report/hcp.htm on the MedWatch Website. Patients' names are kept confidential. Consumers also may call the toll-free MedWatch number or go to www.fda.gov/medwatch/report/consumer/consumer.htm on the MedWatch Website to report an adverse reaction. To file a report, consumers will be asked to provide name, address and telephone number of the person who became ill; name and address of the doctor or hospital providing medical treatment; description of the problem; name of the product and store where it was bought. Consumers also should report the problem to the manufacturer or distributor listed on the product's label and to the store where the product was bought.
The report of the President's Commission on Dietary Supplement Labels, released in November 1997, provides a look at the future of dietary supplements. It encourages researchers to find out whether consumers want and can use the information allowed in dietary supplement labeling under DSHEA. It encourages studies to identify more clearly the relationships between dietary supplements and health maintenance and disease prevention. It urges FDA to take enforcement action when questions about a product's safety arise. And it suggests that FDA and the industry work together to develop guidelines on the use of warning statements on dietary supplement labels.
FDA generally concurred with the commission's recommendations in the agency's 1998 proposed rule on dietary supplement claims.
While much remains unknown about many dietary supplements--their health benefits and potential risks, for example--there's one thing consumers can count on: the availability of a wide range of such products. But consumers who decide to take advantage of the expanding market should do so with care, making sure they have the necessary information and consulting with their doctors and other health professionals as needed. "The majority of supplement manufacturers are responsible and careful," FDA's Yetley says. "But, as with all products on the market, consumers need to be discriminating. FDA and industry have important roles to play, but consumers must take responsibility, too."
Now that you have read and understand this, can you explain what an effective herbal remedy is if it is not a drug? Trying to make sense of the FDA guidelines is like trying to follow the pea in the old 3-shell con game. Now that the FDA has been compromised, the last hope for consumers for honesty in the supplement marketplace lies with the Federal Trade Commission (FTC). In Dietary Supplements: An Advertising Guide for Industry the FTC states:
In 1994, the Dietary Supplements Health and Education Act (DSHEA) significantly changed the FDA's role in regulating supplement labeling. Although DSHEA does not directly apply to advertising, it has generated many questions about the FTC's approach to dietary supplement advertising. The answer to these questions is that advertising for any product--including dietary supplements--must be truthful, not misleading, and substantiated. Given the dramatic increase in the volume and variety of dietary supplement advertising in recent years, FTC staff is issuing this guide to clarify how long-standing FTC policies and enforcement practices relate to dietary supplement advertising.
The FTC points out that it "gives great deference to an FDA determination of whether there is adequate support for a health claim," and "will generally arrive at the same conclusion when evaluating unqualified health claims." FTC even says that there may be instances where a carefully qualified health claim may be allowed in advertising that is not authorized for labeling, but it then drops the hammer by stating: "However, supplement marketers are cautioned that the FTC will require both strong scientific support and careful presentation of such claims." FTC further states that "all parties who participate directly or indirectly in the marketing of dietary supplements have an obligation to make sure that claims are presented truthfully and to check the accuracy of the support behind those claims (emphasis theirs). The FTC's truth-in-advertising law can be boiled down to two common-sense propositions: 1) advertising must be truthful and not misleading; and 2) before disseminating an ad, advertisers must have adequate substantiation for all objective product claims."
Concerned professionals and consumers are urged to help the FTC in its mission by being watchdogs for false and misleading dietary supplement advertising. People are advised to file their complaints in writing, and to send copies to NCAHF. Further, false ads constitute fraud which can also be prosecuted by every district attorney in whose jurisdiction the ad appears.

Although often caricatured as "Uncle Sam," the government is not a person with attributes of character that can be used to define a personality in terms of morality.* The government is a complex network of administrative, legislative and judicial agencies that are often in conflict with each other. Tobacco is treated favorably by the departments of Agriculture and Commerce, and under attack by the Surgeon General and the FDA. In my consumer health work I have come to realize that there are two layers of government--the political and the bureaucratic. The political government is made up of elected people and their appointees. The bureaucratic is made up of civil service workers whose jobs go on no matter who is in power. Their hard work holds the country together, but they can be a real pain when they get bogged down in the process and forget the outcomes their enabling laws intended. The political government is fickle, changing with the cycles of elections. Politicians are faced with the ever-present dilemma of when to lead and when to follow their constituencies. Leadership has never been easy, but in this high-tech era it is near impossible. The constituency is rarely in a mood to be studious. Arousing emotions and following the polls is easier. But, this can be dangerous. The winds of opinion can suddenly shift. When public opinion becomes a sense of outrage, politicians must to be on the right side or they will be swept away. A politician who is out of office is like a policeman without a badge. The bureaucratic government is more powerful in the everyday workings of government than the political layer. The legislators write laws, the courts set the Constitutional limitations of those laws, but the bureaucrats develop the policies that determine how these laws affect the lives of the citizenry. In matters of interest to NCAHF the NIH Center for Alternative Medicine is giving credibility to sectarian medicine, quackery and the mavericks and fringe practitioners who promote them. The NIH Dietary Supplements Commission looks more like something that ought to be in the Department of Commerce as an entity to promote the dietary supplements industry than a part of the National Institutes of Health. At the same time, the FBI is working harder at investigating and prosecuting health fraud, individuals in Congress are trying to find loopholes for their constituents. I continue to believe that the best way for evil to triumph is for good people to do nothing.
